Oral self-inflicted accidental trauma in patients with neurological disorders: a case report of dental management in infants with cerebellar hypoplasia

Self-inflicted oral injuries, accidental or otherwise, can cause major consequences. Measures need to be taken to protect individuals from chronic self-injurious behaviour; however, there are no official guidelines on the subject. The purpose of this article is to show the case of a 1-year-old patient with neurological disorders who, following the eruption of deciduous teeth, had self-inflicted a traumatic ulcer on his tongue and lower lip. Following a multidisciplinary approach involving several operating units of our hospital to make a diagnosis, an oral device was designed to completely cover the dental elements to prevent recurrence of the trauma and to prevent further worsening of the injuries already caused. The purpose of this work is to demonstrate that although the surgical approach, such as extraction of the dental elements, may be the quickest solution in situations similar to the one presented, the high biological cost and irreversibility of the result lead to seeking alternatives and more conservative solutions such as the one described.

A comparison of pediatric ocular injuries based on intention in patients admitted with trauma

Purpose

Pediatric ocular trauma is a major source of morbidity and blindness and the number of epidemiological studies is incommensurate with its significance. We sought to determine differences in epidemiologic patterns of pediatric ocular injuries based on intention.

Methods

A retrospective review of the National Trauma Data Bank (2008–2014) was performed and patients < 21 years old, admitted with trauma and ocular injury, were identified using ICD-9CM codes. Demographic data, types of injury and external circumstances including intention were tabulated and analyzed with students’ t and chi-squared tests and logistic regression. Statistical significance was set at p < 0.05.

Results

Fifty-eight thousand seven hundred sixty-five pediatric patients were admitted for trauma and ocular injuries. The mean(SD) age was 11.9(6.9) years. Most patients were male (68.7%) and White (59.1%). Unintentional injuries (76.3%) were mostly associated with falls (OR = 13.4, p < 0.001), assault (16.3%) with firearms (OR = 9.15, p < 0.001) and self-inflicted trauma (0.7%) also with firearms (OR = 44.66, p < 0.001). There was increasing mean(SD) age from unintentional, 12.9(6.6) years and assault 12.3(8.1) years to self-inflicted trauma, 17(3.4) years. The 0-3 year age group had highest odds of open adnexa wounds (OR = 30.45, p < 0.001) from unintentional trauma, and traumatic brain injury (TBI) (OR = 5.77, p < 0.001) and mortality (OR = 8.52, p < 0.001) from assault. The oldest 19-21 year group, had highest odds visual pathway injuries (OR = 8.34, p < 0.001) and TBI (OR = 1.54, p = 0.048) from self-inflicted trauma and mortality (OR = 2.08, p < 0.001) from unintentional trauma.

Conclusion

Sight-threatening injuries were mostly associated with unintentional trauma in the youngest group and self-inflicted trauma in the oldest group. Patterns emerged of associations between demographic groups, mechanisms, types of injury and associated TBI with intention of trauma.

Intractable Postoperative Wounds Caused by Self-Inflicted Trauma in a Patient with Cutaneous Munchausen Syndrome Presenting as a Pyoderma Gangrenosum-Like Lesion

A 50-year-old Japanese woman consulted the emergency department of our hospital for bleeding due to an intractable postoperative wound on the lower abdomen; the postoperative wound was owing to a laparoscopic cholecystectomy performed 1 year previously for acute cholecystitis. She presented with a painful ulcer on her right lower abdomen. She also presented with multiple scars, skin grafts on the extremities, and a missing left lower leg, the causes for all of which were unexplained. The results of her blood test were normal, except for the hemoglobin level. Histology of the skin biopsy specimen from the ulcer did not show any specific findings. The previous surgeon who had performed the laparoscopic cholecystectomy revealed that surgical wound dehiscence had occurred during her admission. After a body restraint had been applied, the ulcer improved. Medical records indicated that she had been admitted to the department of plastic surgery at our hospital for skin grafting of a leg ulcer. During that admission, she refused to consult with the department of psychiatry, al-though the staff suspected mental disorders. Therefore, we diagnosed her with cutaneous Munchausen syndrome. After vacuum-assisted closure (VAC) therapy had been performed to prevent her from traumatizing the ulcer again, it rapidly became granulated and reepithelialized. Munchausen syndrome is characterized by feigning physical symptoms to seek attention. Patients self-inflict numerous lesions, keep getting admitted to different hospitals, and feign acute illness, usually spectacular diseases. VAC therapy may be effective for preventing patients with cutaneous Munchausen syndrome from traumatizing their wounds.

Successful treatment of self-inflicted tongue trauma patient using a special oral appliance

A 7-year-old male presented with a painful ulcerative lesion on the right lateral tongue and left lower buccal mucosa due to self-inflicted trauma. Antibiotic medication and use of a mouthwash agent were not effective. We made a special oral appliance to cover the maxillary arch and teeth to protect the tongue. The patient showed immediate improvement and did not suffer from any complications. Invasive procedures such as biopsy were not needed. We believe that accurate clinical diagnosis is important and treatment with an oral appliance is effective in self-inflicted oral trauma in children.
